So What is Convection ? Convection Is The Transfer OfHeat From One Place To AnotherBy The Movement Of Fluids.(Example;Liquids,Gases) So How Does Convection Takes Place ?-Convection Takes Place Due To The Expansion Of The Fluid.When The FluidIs Hot, Its Volume Will Increases.This Means Its Density Had Decreases... Next,The Less Dense Fluid ThenRises And Floats Up While The DenserFluid Flows In To Its Places.This Is Convection. We Are Coming To The End Of ThePresentation.. Let Us Present YouGuys A Video On Convection :) -End-Thank You For Your Attention :)MadeBy:John(38) ,Ivan(28)Researcher:Kai(25),Daniel(22) Convection[Group9]Daniel,Kai,John,Ivan Did You Know !?A Boiling Water Is An Example Of Convection.Yes!First The Heat Passes Into The Water By ConductionThrough The Metal Of The Heating Element. Question That Was Ask Frequently By People-Can Convection Take Place In Solid ? The Answer Is No. But Why ? (Because Neither Bulk Current Flows Nor Significant Diffusion Can Take Place In Solids Unlike Fluids.)If You Dont Understand What (...) Means It Simply Say That Convection Currents Occur As A Result Of The Movement Of A Body.Since Solid Cant Move So Convection Only Occur In Fluids And Not Solids.
